Craig Sager hugs it out with Team USA before Rio

Well-respected sideline reporter Craig Sager is undergoing treatment for leukemia, and won't be able to cover Team USA when it heads to Rio. So when the team played its final exhibition game Monday night in Houston, Sager was in the locker room to wish the players well before they leave.

The sideline reporter known for his wacky fashion sense was initially set to cover basketball for NBC during the Olympics. But he needs a third bone-marrow transplant, and he won't able to join the network.
